Serenity Coral Sand 1-2mm 10kg
Create a healthy, natural environment for your aquarium with Serenity Natural Aragonite Coral Sand 1–2mm, a premium substrate made from 100% natural aragonite coral. Perfect for marine, reef, and freshwater aquariums that require a higher pH, this fine-grain sand provides a stunning natural appearance while delivering important benefits for long-term water stability.
Unlike inert substrates, aragonite is naturally rich in calcium carbonate, helping to buffer and stabilise pH while contributing calcium and carbonate to support healthy marine environments. This makes it an excellent choice for reef aquariums, fish-only marine systems, and freshwater aquariums housing species that thrive in harder, more alkaline water, such as African cichlids.
The carefully graded 1–2mm grain size creates a comfortable substrate for sand-sifting fish, gobies, jawfish, wrasses, and burrowing invertebrates, allowing them to exhibit their natural feeding and digging behaviours. It is also ideal for use in deep sand beds, plenum systems, and as biological filter media, where its large surface area supports the growth of beneficial bacteria that help maintain excellent water quality.
Each batch is triple washed and graded to minimise dust and ensure a clean, ready-to-use substrate that settles quickly and creates a bright, natural-looking seabed. Whether you're setting up a new reef aquarium or upgrading an existing tank, Serenity Natural Aragonite Coral Sand 1–2mm offers the perfect combination of natural beauty, reliable water chemistry support, and long-lasting performance for a healthy, thriving aquarium.
